functional location for a tag number is it’s unit number, for a unit number it’s a system number and so on.
See example in 5.2 SAP Asset Register / Functional Location Hierarchy / Structure on page 78.
In cases where the tag number is part of a skid or package the skid may be the superior functional location (Unit) for the tag and shall be given a unit number corresponding to skid’s primary tag number.
Example 1: Compressor Package
The examples above show tag numbers having a superior functional location (Unit) that is di-rectly related to the overall operation/functionality of the package, (the compressor). The same philosophy is therefore employed when establishing unit numbers for other tagged items, even when they are not procured as a complete package unit. For example, vessels will always have directly related instrumentation.
The vessel tag number will then form the basis for the unit number for the instrumentation and the vessel itself.
The example below highlights some tag numbers on a separator and their superior functional location (unit number):
Example 2: Separator
Important Notes
The format of the unit number consist of Company Code/Facility/System/Unit Number, where unit number is equal to a tag number. Between category code and sequence number is a space, and structure indicator for Functional Locations above tag level is UKNO1 in SAP.
Note from the examples above that the tag number and unit number for the "main" items are the same.
Note that physical boundaries have no impact on the relationship between tag numbers and unit numbers. This is entirely related to operation and functionality.

Where a single skid or package unit contains parallel, main tagged items (e.g. three identical pumps), each one will be tagged separately and therefore each unit number will be separate.
See example below:
Example 3: Identical pumps mounted on one skid:
5.4.1 General Unit Numbers / “stand alone” Tagged Items
Many tagged items do not relate specifically in a functional or operational sense to a unit. How-ever, this is a mandatory field and therefore a general number is applied. Three general rules apply to the allocation of general unit numbers as shown below:
1. The tag number and unit number are the same except for objects that have an alpha prefix.
These will loose the alpha prefix in the unit number.
2. The unit number is the panel tag number to which the tags are connected.
Typical examples of tags which fall into this category of having no natural superior functional location (unit) are light fixtures.
The emergency light fixtures for an entire platform might have tag numbers
27- 00015 to 27-01830. The unit number for all of these might then be BD/EKOJ/740/28 05005 which is the panel supplying power to the light fixtures. If there are more than one pan-el the tags shall be assigned to the panpan-el they are supplied from. Normal light fixtures in sys-tem 670 would also be handled in this way.

System 730 unit numbers shall as a minimum be segregated as in the following examples where applicable:
Note:
If a dedicated control panel exist, this panel’s tag number shall be included under the unit number for its detectors.
For gas detectors it is preferred that a unit number for each type of detectors is created. I.e. IR line detectors, IR point detectors, catalytic detectors and acoustic detectors.

5.4.2 General Unit Numbers for Telecommunication & Computer Systems (860, 870 & 880)
The communication systems 860, 870, 880 on all platforms are utilizing a common system for Superior Functional Location Unit numbers, which originates from the old Maintenance Planning System. These Superior functional Location Unit numbers deviates from the standard way of allocating Unit numbers.
For the 860 and 870 systems these unit numbers are generated in the 80-category, and normally sequence numbers start with” 80 5”, and the two last digits are the same for every platform.
For the system 880 these unit numbers are generated in the 13-category, and normally sequence numbers start with “13 5, and the two last digits are the same for every platform.
The existing range of unit numbers is shown in the tables below.
Please contact the System/Technical (SA/TA) Responsible persons for these systems, before issuing new unit numbers, if additional unit numbers are required. Remember that the unit numbers listed below are used as main Reference Object Functional Locations for the Telecommunication Preventive Maintenance Program, and it is therefore, important that tag numbers are correctly linked against these units.
Tag numbers belonging to the 860 and 870 systems will normally be allocated inn the
80-category, and tag numbers belonging to the 880 system will normally be allocated in the 13 category. They will utilize a prefix system as described in 5.11.13 Alpha Prefix Legend - Cate-gory 13 & 80 Communication (telecom) Equipment on page 162.
However, since data communication and telecommunication systems are more and more integrated, tag numbers might have been allocated in either the 80 or 13 categories depending on traditional views of belonging. Therefore both 13 and 80 category tag-numbers within these tree systems might, when relevant, be linked to super functional unit numbers in the opposite category.

5.5 Tag Number Structure in SAP
The Functional Location level tag in SAP consist of:
Company code/Facility/Tag number.
(Structure indicator for Functional Location tag level is always UKNO2 in SAP).
There is always a space between the category code and the sequential number.
Examples are as follows:
• For more detail concerning piping tag numbers see Equipment Category 60.
The tag number structure is a combination of either 2 (min.) or 3 (max.) data elements as described in the sections above. Exception to this principle is:
• MCC Cubicles in MCC panels have an extra alpha suffix - see 5.10 Category Descriptions and Tag Number Requirements on page 103 under category 28 (MCC/Switchboard Cubicle Numbering).
• Piping for some vendor given line numbers.
In SAP both company code and facility code is registered in the same field and the structure are i.e.:
Either Company/Plant/Category code + Sequential number (minimum)
Or Company/Plant/Category code + Alpha prefix + Sequential number(maximum)
Tag numbers shall be consistent in appearance on drawings/documents, nameplates and in the asset register.
Note: The specification for tag nameplates and labels is covered in 5.14 Specification for Tag Nameplates & Labels on page 183.
Extended SAP hierarchy / multi level units:
Within some specific equipment/- category codes(75 (lifeboats) & 28 (panels)), it is mandatory to extend the SAP hierarchy to several levels to describe the different relations between the technical objects. It may be beneficial to extend the SAP hierarchy also for other type of equip-ment. In this case it must be clarified with the System / Technical responsible person/s.
The examples below describe current requirements for extended SAP hierarchy.
BD/EKOJ/67 00068 BD/ELDA/43 TT-6886
BD/EKOJ/60 210-001 (system on EKOII installations and newer)*
BD/EKOK/60 5623 (system on EKOI installations)*
BD/EKOF/60 20-E-113 (system on EKOI, when vendor has allocated line number, typical)*

Example 2 – Extended SAP hierarchy – electrical equipment:
5.5.1 Tag Sequence Number
In addition to the equipment category code, (and the secondary alpha prefix described in 5.7 Secondary Alpha Prefix on page 95 where applicable), all technical objects have a sequence number (new sequence number shall always contain 5 digits, old sequence number will vary, and can be up to 5 digits). For all categories except instruments, this sequence number is non-intelligent (see examples in 5.12 Example of Tag Syntax for Typical Equipment Categories on page 168).
For instruments only (exept, see example 5.6 Category Codes on page 93, only wanted for new platforms), the sequence number for all instruments in one loop shall be the same.
Because of this, it is permitted that an additional one character alpha suffix may be added in the event that there are two or more instruments with the same function prefix (i.e. secondary alpha prefix) in the same loop.
See examples in 5.12 Example of Tag Syntax for Typical Equipment Categories on page 168.

Technical Object Numbering/Tag Numbering 91 236
Sequential numbers are allocated per platform, per category directly in SAP.
5.5.2 Tag Descriptions
Tag descriptions consist of the following elements in the order shown below:
1. Type of object 2. Function/service 3. The object it service
All tag descriptions in SAP shall be in English and in capital letters.
Tag description field in SAP asset register contains 40 characters, use abbreviations listed in section 7 Abbreviations - Document/Drawing & Equipment Module on page 219 if adequate.
When referencing a tag number that contains an alpha prefix, the category code may be omitted if place so requires, i.e. PT-01234. When referencing a tag number not containing a prefix the category code must always be included, i.e. 67 01234.
Area code shall not be included in the tag description except for MCC cubicles and circuit break-ers. In this case the Location field in SAP will identify the location of the MCC, hence it is useful to identify the area where the object being supplied is located.
Use of ”Long text” field for long tag descriptions in SAP asset register is not acceptable, because information can not be listed in reports. See following examples:
Note: Tag description in the PCSS system must be in accordance with the PCSS procedure.

Technical Object Numbering/Tag Numbering 92 236
5.5.3 Other General Information
Before data transfer of tag numbers to the Asset Register, the unit numbers need to be pre-registered by the COPNO’s Asset Register Coordinator or the unit number must be located in the load file in front of all tag numbers that refer to this unit.
For modification projects where object is removed or disconnected, the design contractor shall maintain a tag register, not only for new objects, but also for all objects which have been removed. This is to enable updating of the asset register on completion of the project.
All objects scrapped in -situ will be labeled in accordance with procedure 2805 "Utstyr som settes permanent ut av drift."
5.5.4 Future tag
Future tag shall be registered as any other function locations, but shall be marked with a specific status code (INAK/PLHO). See section 6.1 General on page 201 concerning drawing details.

5.6 Category Codes
All unit- and tag numbers shall be prefixed by a two (2) digit equipment category code followed by a sequence number separated by a space. Some categories also require an alpha prefix in front of the sequence number. A full list of the valid codes appears in section 5.6.1 Valid Cate-gory Codes on page 94, and expanded descriptions of each of the categories appear in Section 5.10 Category Descriptions and Tag Number Requirements on page 103.
It should be noted that COPNO does not recognize technical object "Packages" or "Skids” as equipment categories. They are always tagged and registered as a combination of individual equipment categories.
For example:
A compressor package would typically consist of various equipment categories:
A pump would typically consist of various component categories and a operated valve would consist of component categories 91 and 43:
By using the same sequence number for different equipment categories it take a lot of administration time, therefore only preferred for new installations.
See 5.5.1 Tag Sequence Number on page 90.
Category 16 - Compressor
Category 60 - Piping & Pipeline System Category 63 - Gearbox
Category 43 - Various instruments Category 84 - Turbine
Technical Object Numbering/Tag Numbering 94 236
Note: Even though ”package” or ”skids are not registered as unique entities, it is required that individual tagged items are related to unit items for future maintenance planning purposes.
However, this is achieved within a data base environment and is explained fully in section 5.2 SAP Asset Register / Functional Location Hierarchy / Structure on page 78.
